Hobbyist and toy collecting

You can use 3D printers to make moulds I would think.

Yeah, I see where you are coming from now. I agree.

Additive manufactureing has advanced to that point but it simply takes too much resources and is only available for rapid prototyping and models. The prints can't handle some of the stresses that normal subtractive manufacturing could handle.

There were stamp collectors and people like that in the USSR.

There are specialized 3d printing systems that can print load bearing parts of aircraft. Of course, your typical weeb won't want or need such a device.

That's just plain wrong. Additive printing, by its very nature, uses less resources, since you are adding material instead of removing it.
